For comet scientists, elation and redemption at Philae’s wakeup

19 June 2015 Stephen Clark

Research teams across Europe spent the last half-year meticulously going through a wish list of experiments for the Philae comet lander without knowing whether they would ever get a chance to execute the tasks.

Engineers seek to stabilise radio link with comet lander

16 June 2015 Stephen Clark

Emboldened by renewed contact with Europe’s comet lander, engineers are repositioning the mission’s Rosetta mothership this week to establish a reliable a communications link with the dishwasher-sized Philae landing craft, a prerequisite for resuming a science campaign abbreviated by a power shortfall last year.

Tour comet 67P/Churyumov–Gerasimenko in Rosetta’s latest image release

1 June 2015 Stephen Clark

The latest batch of images released from the European Space agency’s Rosetta mission shows the brutal gray landscape of comet 67P/Churyumov-Gerasimenko in vivid detail.

Rosetta keeps its distance from awakening comet

13 April 2015 Stephen Clark

Mission controllers are rethinking a series of close-up comet flybys planned for Europe’s Rosetta spacecraft after a haze of dust around the comet’s central nucleus led to navigation errors during a close encounter in late March.

Diverse destinations considered for new interplanetary probe

12 April 2015 Stephen Clark

Science teams from across the United States have submitted 28 proposals for missions to explore the moons of Jupiter and Saturn, touch the asteroid-like satellites orbiting Mars, visit unseen worlds and hunt for objects that could strike Earth one day.

Rosetta probe disoriented by comet dust

6 April 2015 Stephen Clark

Ground controllers are analyzing a fault aboard Europe’s Rosetta spacecraft after an encounter with comet dust confused the probe’s navigation system, leaving the robot explorer in a temporary safe mode and halting regular science operations.

Rosetta begins listening for signs of life from comet lander

14 March 2015 Stephen Clark

Europe’s Rosetta spacecraft is trying to contact the Philae landing probe for the first time since the robot fell silent after a bouncy landing on a comet in November.

Rosetta glimpses its own shadow on comet 67P

4 March 2015 Stephen Clark

The sharp-eyed science camera on Europe’s Rosetta comet orbiter caught a view of the probe’s fuzzy shadow when controllers guided the spacecraft just a few miles over its subject’s nucleus last month.

Rosetta closing in again on comet

25 February 2015 Astronomy Now

After a close up fly by of comet 67P/Churyumov–Gerasimenko on Valentine’s Day, Rosetta looped further away from the comet than it has been since arriving there and returned some dramatic new images.

Photos from Rosetta’s Valentine’s Day comet close-up

17 February 2015 Stephen Clark

Europe’s Rosetta spacecraft — six months into its research mission at comet 67P/Churyumov-Gerasimenko — made its closest flyby of the comet’s boulder-strewn nucleus Saturday, capturing new photos and measurements to help scientists unravel how the duck-shaped body is evolving on its orbit around the sun.
